I works really well for me. The unique card number for each site is a great security layer. Awesome!

Update Jan. 2026:
The extension works so infrequently that I can't believe this is a product they still want users to install. Whatever is going on at Capital One, they've abandoned making this product stable and reliable, which is a real disappointment. I used to really enjoy using the virtual CCs for online transactions, but at this point I'm having to go to the CapOne website to manage and retrieve them.

This extension has been adding more and more RUM telemetry components, which access more and more random URLs behind the scenes, and the actual functionality of the app has been declining constantly. Every time I try to use the extension lately, I get the "Checking Session" message and it just constantly spins. And accessing the virtual card list from the website is such a pain that at this point they're useless.

For the past month or so, Eno will not generate the virtual card numbers I already have, forcing me to reenter my credit card numbers time and again.

Works great for me so far. Happy to use an Add on to save using my real credit card number on every site

Really appreciate ability to not expose my credit card number. They finally fixed sign in to use browser login so I don't have to copy/paste my random password from a password manager. Really recommend.

Fails to log in 95% of the time. Capital one website shows virtual cards, but doesn't allow creation of them without this god-awful add-on. Great idea, horrific execution.

We don't like to give ANY info online

Spent the 30 minutes to do the 15 convoluted steps to set this all up, and of course it doesn't work. BofA had a much nicer setup, that didn't need a lame plugin. I would not be suprised if they are sniffing all your web browsing with this either. zero stars

The number did not work when I tried it. I deleted the number thinking I could recreate it. NOT.
